and here is an experiment which we can all try at home. Shall we? First, you need to go to your local hardware store and buy a sledge hammer. Next, you need to use this sledge hammer to pound a huge hole in your bedroom wall. Take a look inside the hole in the wall and you will notice that there is a hollow space which runs the entire length and height of your wall. This is known as the crawl space because there are creatures crawling in there. Next, I need you to make a list of everything you see inside this crawl space and report back to me.
